Protein-Protein Docking

Informatics-driven Protein-protein Docking


Highlight of work led by I. Hashmig and A. Shehu* at ACM BCB-W Comput Struct Biol Workshop 2013, Proteome Sci J 2013, IEEE Intl Conf on Bioinf and Biomed (BIBM) 2012, J Bioinf and Comp Biol 2012, and IEEE BIBM-W Comput Struct Biol Workshop (CSBW) 2011.


We also design probabilistic search algorithms for the protein-protein docking problem. The goal is to predict functionally-relevant structures of assemblies formed by two or more protein units. This is an important problem, as molecules come together in higher-order structures to participate in chemical processes in the cell. Our approach is to separate the problem into two stages. The objective of the first stage is to map the configuration space with powerful probabilistic search algorithms. The key idea is to employ information on putative interaction interfaces in order to expedite the search and sample promising configurations in a rapid manner. The objective of the second stage is to integrate more sophisticated energy functions for refinement of selected promising structures. Details on this line of work can be found under the related pages and publications on our website.
